-Subject: [PATCH 1/2] ARM: imx6ul: Add support for liteSOM
-
-liteSOM is a System On Module (http://grinn-global.com/litesom/). It
-can't exists on its own, but will be used as part of other boards.
-
-Hardware specification:
- * NXP i.MX6UL processor
- * 256M or 512M DDR3 memory
- * optional eMMC (uSDHC2)
-
-Here we treat SOM similar to SOC, so we place it inside arch/arm/mach-*
-directory and make it possible to reuse initialization code (i.e. DDR,
-eMMC init) for all boards that use it.

-+How to use U-Boot on Grinn's liteBoard
-+--------------------------------------
-+
-+- Build U-Boot for liteBoard:
-+
-+$ make mrproper
-+$ make liteboard_defconfig
-+$ make
-+
-+This will generate the SPL image called SPL and the u-boot.img.
-+
-+- Flash the SPL image into the micro SD card:
-+
-+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
-+
-+- Flash the u-boot.img image into the micro SD card:
-+
-+sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
-+
-+- Jumper settings:
-+
-+S1: 0 1 0 1 1 1
-+
-+where 0 means bottom position and 1 means top position (from the
-+switch label numbers reference).
-+
-+- Insert the micro SD card in the board.
-+
-+- Connect USB cable between liteBoard and the PC for the power and console.
-+
-+- U-Boot messages should come up.
